setup_store(store=None)[source]

Setup results store

setup_cache(start_idx: int = 0, end_idx: int = -1, only_h: bool = False)[source]

Setup cache from start_idx result to end_idx result

if only_h is True, only waterdepth is loaded into memory

Parameters:

  • start_idx – start index (0-based)

  • end_idx – end index (0-based)

  • only_h – only waterdepth is loaded into memory
